Booking.com interview questions

There are 4 stages: HR, on-the-spot business case, take-home case, hiring manager round. At case stages, they give random problems that aren't related to the job description necessarily. You are expected to devise solutions to those and they ask you a lot of questions around it, fine. I made it to the final round with the hiring team where they ask behavioral questions, and they had a negative attitude from the start. They asked questions in a way that shows they haven't even properly read my resume, criticising my answers saying "why did you give example from this project?", although that project was very similar to what job description entailed. I've found their attitude a little disrespectful. At the end they compiled negative feedback from all rounds, and then they ghost you when you ask if you've passed the previous case rounds to reach the final round or they just did all the interviews regardless of pass/fail. They also haven't provided any positive feedback, leaving a placeholder in their email. They should treat candidates better, bring a better attitude to the interviews.
